Q

A 40 year old lady develops progressive dyspnea and hemoptysis of 1 week. On further history, she reports tea-colored urine. Her condition worsens, and she dies.

Q

A 41 year old asymptomatic woman presents with a nodule on a routine xray. CT scan showed a 3-cm bronchial mucosal plaque penetrating the bronchial wall and fanning out into the peribrochial tissue, resembling a collar button.

(A) 70-80%% of patients with this tumor have hilar node metastasis at presentation (B) the tumor is thought to arise from the Kupffer cells that line the bronchial mucosa (C) Patients commonly present with the syndrome of diarrhea, flushing, and cyanosis (D) it can be considered as a less aggressive cousin to small cell carcinoma, both belonging in a spectrum of pulmonary neuroendocrine neoplasms

A

it can be considered as a less aggressive cousin to small cell carcinoma, both belonging in a spectrum of pulmonary neuroendocrine neoplasms (A- 5-15% nodal metastasis; B - arises from Kulchitsky cells; C - rarely presents with the syndrome) (TOPNOTCH)Robbins Basic Pathology, 8th Ed. Pp 534

Q

A 28 year old man complains of epistaxis of one month duration.
